We use Inception Score(IS) [1]}, Structural Similarity(SSIM) [2]}, Frechet Inception Distance(FID) [3]} and
Learned Perceptual Image Patch Similarity(LPIPS) [4]}
to quantitatively evaluate the quality of the generated image, which are commonly used evaluation metrics in image generation task. For IS and SSIM, a higher score is better. For FID and LPIPS, a lower score is better.
